Title: An improved combined edge gummer and perforator
IPC: B43M5/00
Filed: 1925-11-09
Abstract: 254,168. Fox, F. E. T. Nov. 9, 1925. Affixing by adhesives. - A combined machine for uniting the edges of paper sheets in accurate alignment, and for perforating the united sheets in a line parallel to the gummed edge, comprises a gummer which collects liquid gum from a roller and deposits it on the top edge of the bottom paper sheet, the top sheet being held in adjustable fingers let into an adjustable backlay. A travelling table supported between rigid traces conveys both sheets to rollers which unite them and pass them to perforating rollers. The relative adjustment of the sheets is controlled by a side-gauge and by the back-lay a rear table track providing that the sheets are perforated parallel to the gummed edge. As shown in Fig. 1, a metal table c, which reciprocates between tracks d, d<1> formed on a base plate b, carries a gauge e, adjustable by slotted guides f, f<1> and set-screws g, g<1> to act as a side-lay for the paper sheets. A back-lay h, pivotally secured to the table c by a pin i, is similarly adjustable. Two sets of T-shaped fingers l - - m - - shown in Fig. 2, are let into the face of the back-lay h and secured by spacing blocks n - -. The fingers extend in a forward direction over the table c, flat springs o - - ensuring the passage of the gummed bottom sheets beneath the fingers to the rollers p, p<1>. Arms x, x' on a shaft y, Fig. 1, pivotally carry a gummer u which is constrained to perform an arcuate movement by a sliding piece attached to the gummer and working on a pivoted bar. A gum trough, with a rotating roller which contacts with tongues on the gummer u, slides in a track fitted adjacent the back-lay h. The feed rollers p, p' and the shafts N, N' carrying the perforating wheels 0, 0<1>, Fig. 7, are connected with the driving shaft R, and by synchronizing gears and a clutch Y, driven from the shaft R, is adapted to be withdrawn by a pivoted interceptor 2, operated by a pedal 4, to disengage a spring-pressed plunger Z from the clutch block. One complete turn of the clutch shaft imparts a half turn to a main shaft 7 which carries discs 8, 8<a> with pins 9, 9<a> respectively, as shown in Fig. 4, the pins 9, 9<a> alternatively engaging a pin on a disc 10 formed on a rocker shaft 11 which imparts a rocking motion through gearing to the shaft y and operates the gummer u. The shaft y carries an eccentric and pawl which engages a. ratchet wheel to actuate the gum roller in the track. Levers 29, 29a on the shaft 7 intermittently engage dogs on the table c through slots in the base-plate b to impel the table forward at each half turn of the shaft 7, the return stroke of the table being effected by springs.

Title: Method of and apparatus for measuring a changing dimensio
IPC: G01B7/12
Filed: 1976-08-18
Abstract: 1505168 Measuring the varying diameter of a reel MASSON SCOTT THRISSELL ENG Ltd 18 Aug 1976 [5 July 1975] 28452/75 Heading G1N The invention relates to an apparatus for and method of determining the diameter of a reel 1, 2 paying out or taking on a web of sheet material. The apparatus comprises a sensing wheel or roller 10 for rotation by the web, pulse generating means associated with the sensing wheel or roller 10 and arranged to provide a constant number of pulses per revolution, means e.g. transducers 3, 4 and counters 5, 6, for determining a number of revolutions of the reel, and means, e.g. a four decade counter 13, for counting the pulses during the number of revolutions and from that count deriving the mean diameter of the reel. Means may be provided for repeating the pulse count each reel revolution. An indicator 17 is provided for displaying the mean reel diameter. The indicator 17  is fed from a memory circuit 15 via a de-coder 16, the memory circuit being reset after a predetermined number of reel rotations. A signal representing the instant reel diameter is compared with a reference signal representing a reference diameter in a comparator 18 such that a trigger signal is generated when the two signals achieve a predetermined relationship. For calibration a correction circuit 12 is interposed between the pulse generating means and the counting means such that, in use, the pulse count per reel revolution gives a direct indication, or a simple multiple or fraction of the mean reel diameter. When a reel is initially rotated the apparatus may not give a true reading and thus a delay circuit is provided for preventing full operation of the counting and diameter deriving means for a given period after the commencement of the reel unwinding or winding operation. The aforesaid trigger signal may cause the changeover from one reel to another through a circuit 20 and also may cause the splicing of the web of the "spent" reel in an unwinding operation to the web of a "full" reel through a timer 21 and splice relay 22.

Title: Improved apparatus for the measurement of insulation from earth of electrical networks
IPC: H02H3/17
Filed: 1963-07-22
Abstract: 1,018,681. Measuring insulation and resistances. CHARBONNAGES DE FRANCE. July 22, 1963 [July 24, 1962], No. 28995/63. Heading G1U. An apparatus for measuring the insulation resistance to earth of an alternating current network 2 (shown as a 3 phase supply) with an insulated neutral, and which permits an accurate measurement to be made irrespective of voltage variations in the network, includes a circuit 14 which supplies a d.c. voltage proportional to the voltage of the network, a coupling 3 including a resistance 10 connected via rectifiers between the phases of the network and earth across which is derived a voltage proportional to the current flowing through the coupling, a circuit 18 including a capacitor which is alternately charged to the voltage proportional to that of the network and then discharged to the voltage proportional to the current through the coupling; and a device for measuring the discharge time of the condenser, which will be a function of the insulation resistance to earth of the network. The current through the polarized coupling 3 will be increased as the insulation resistance decreases and hence the voltage U D  across the resistance 10 will be related to the insulation resistance. However it will also depend on the network voltage. A voltage proportional to the network voltage may therefore be used to supply a multivibrator arrangement including the transistors 19A, 19B, and the voltage U D  may be applied to the transistor bases. The charge and discharge times of the multivibrator capacitors 11A and 11B depend on the difference between these two voltages, which is related to the insulation resistance, so that the output frequency of the multivibrator depends only on this resistance. A measurement of this frequency therefore yields the required information. The frequency signal may be transmitted over transmission lines to a distance and still faithfully retain the information. A simpler circuit incorporating a mechanical switch and a single capacitor 11 is described (Fig. 1 not shown). The network voltage and the voltage U D  are alternately switched to the capacitor, whose discharge time may be read directly by a device such as a ballistic galvanometer connected across it.

Abstract: 506,572. Telegraph exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Oct. 7, 1938, No. 29133. Convention date, Oct. 15,1937. [Class 40 (iii)] . An automatic transmission of telegraphic impulses from an exchange to a wanted line Y initiates the transmission of a signal to the calling line x when the wipers of a final selector FS come to rest on the contacts of a wanted unengaged line. When the brushes of a line finder LF find a calling line, a relay Ccr extends the line to a controlling circuit and sends back a signal to start the caller's teleprinter motor. Dialling impulses are received by a relay Dir which sets a group selector GS and the final selector. The controlling circuit then connects earth to a wire C to operate a relay Esr. An interrupter Q is connected to, and closes, a relay Ar, which locks. This connects the contact of a relay Ir to the called subscribers' line. When the contact of an interrupter P is closed, the relay Ir closes its marking contact, and when the contact of the interrupter is open, the spacing contact is closed. The interrupter sends a letter-shift signal, followed by a " Who are you ? " signal. An interrupter R then closes its contact to operate a relay Br, which locks and disconnects the relay Ar. It also earths a wire B to release the controlling circuit. The signal starts the called subscriber's " answer back " device, and the signals thus sent are repeated by a relay Rr2 to the calling subscriber.
